This invention relates to a three-way chase locking device used byprinters, which is of value in not only making a very rapid looking ofset-ups of type or their equivalent in a printers chase, but is ofutility to compensate for various minor discrepancies in dimensions ofset-ups, a number of them, which may be-located in a chase so that eachof the set-ups is in effect individually acted upon by the lockingmechanism and none of the set-ups will be loose while others areproperly locked in position.

In the present invention the type or other set-ups which are used are ofsubstantially uniform size, and a number. of them, four usually thoughthe number may be increased or diminished, may be located in the chaseand with our locking mechanism the same may be independently acteduponat a side and at an end of the set-ups to securely hold the same inplace. The invention. is especially useful in connection with printingthe pages of directories, such as telephone and other directories,though in no sense'limited thereto; as books of any size having uniformsizes of pages may have set-ups alike as to size for the pages thereofand the chase locking apparatus of our invention is readily applicablethereto.

It is an object and purpose of the present invention to provide a chaselocking apparatus whereby a rapid change of set-upsin the chase andlocking of the new set-ups in place is attained with a surety that eachof the setups located in the chase will be properly held. Many otherobjects and purposes will be apparent and may be understood from thefollowing description of the invention taken in connectionwith theaccompanying drawing, in which,

Fig. l is a plan view of a chase having a plurality of set-ups lockedtherein by use of our invention, and

Fig. 2 is a fragmentary enlarged plan illustrating the manner in whichthe locking mechanisms are operated by means of anoperating keytherefor.

tangular shape and formis made of any suitable material. It has parallelspaced sides 1 and, likewise, parallel spaced ends 2. The chaseordinarily has a sheet metal bottom but the details of construction ofthe chase are not important in the present invention, and

will not be specifically described herein. 7

Substantially mid-way between the'ends of the chase and extending acrossthe same is a dividing bar 3 connected at its outerends. to"

4 at their inner. sides two bars 5 are located at a each side of thedivision bars 3, one against the inner side of each of the set-ups 4.The opposite sides of the bars 5 are provided with wedging or lookingprojections 6, having inclined sides as shown, a plurality of the parts6 being located lengthwise of each bar 5 in spaced relation thereon.

Between each of the pairs of the bars 5 a looking bar 7 islocated of theshape shown, and which is provided with cooperating vvedging surfaces 8to engage with the wedg:

ing surfaces 6 on-the bars 5 whereby, when .7

the locking bars 7 are drawn'in one direction, 7

said bars 5 are forced away. from each other 7 against the inner sides*of the set-ups 4i press ing the same very securely against theinnersides of the chase sides 1. J

At theadjacent ends of each of the locking bars 7 a rack member 9 issecured The racks extend by'each other with the teeth of the racksfacing each other. These rack bars pass underneath plates 10 of metalwhich partly bridge the gap over the adjacentrecess ends of thedividingv bar of the chase.

The plates 10 have a spacetherebetween for the passage of an operatingkey 11, shown in cross section in Fig. 2, as in the shape of af0ur-toothed pinion, preferably, and engaging with bothof the rack barsand operating the same simultaneously in opposite directions, wherebyall of the set-ups l: in a chase other the chase set-ups are located attheir may be tightened and locked at their sides by a single operationof the key 11 passing through the opening in the plate 10 and engagingwith the racks 9.

The ends of the set-ups t opposite those bearing against the dividingbars 3 are spaced from the ends 2 of the chase, in which spaces twopairs of bars 15 with wedging projections 16 at theirinner sides arelocated. Locking bars 17 having cooperating wedging parts 18 thereon arelocated one between each pair of bars 15. The locking bars 17 likewiseare provided with rack members 19 passing byeach other and engageablebythe same key 11 to reciprocate the same. Said rack bars 19 are guided attheir free ends in suitable guides-20. 'l Vith this construction, withone operation "of the key 11 to draw the bars 7 toward each sides, whilewith two additional operations, one at each end of the chase to operatethe two pairs of locking bars 17, one pair being at each end of thechase, the ends of the setups are engaged and pressed into secureholding engagement with the dividing bar 3.

Such a construction compensates for minor discrepancies in the outerdimensions of the set-ups 4. We have heretofore filed an application forpatent having Ser. No. M0351 and filing date of March 31, 1930' in whichall of the locking members, those extending lengthwise of the chase andthose at the ends of the chase are simultaneously operable by one keyoperation. In some instances small discrepancies in the outerdimensionsof the set-ups 4: cause some of the set-ups to be firmlylocked and others to be less firmly locked either at a side orend butwith the present invention this will not occur. With the presentinvention the quick and ready assembly or release of the set-ups may behad, as is very evident; Also, the present invention is advantageousover the application previously-referred to as the set-ups 4' can bemade longer, as less'end space is required for the herewith disclosedthree-way chase lock ing mechanism than was needed for the togglearrangement formerly set forth. The invention is defined in the appendedclaims and is to be considered comprehensive of all forms of structurecoming within their scope.
